Awake Proning in COVID-19 Patients With Hypoxemic Respiratory Failure

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT04408222

Brief Summary:
The purpose of this study is to retrospectively review clinical data to determine whether awake proning improves oxygenation in spontaneously breathing patients with COVID-19 severe hypoxemic respiratory failure.

Condition or disease Intervention/treatment
Oxygen Deficiency Coronavirus Infection Other: Awake proning

Detailed Description:
Critically ill patients with coronavirus disease 2019 (COVID-19) severely strained intensive care resources in New York in April 2020. The prone position improves oxygenation in intubated patients with acute respiratory distress syndrome. The investigators wanted to study whether the prone position is associated with improved oxygenation and decreased risk for intubation in spontaneously breathing patients with severe COVID-19 hypoxemic respiratory failure. Awake prone positioning was implemented based on the health care provider decision.

Group/Cohort Intervention/treatment
Awake Proning
COVID-19 patients with hypoxemic respiratory failure with awake prone positioning, as tolerated, up to 24 hours daily.
Other: Awake proning
Prone positioning of awake, as tolerated, for up to 24 hours daily.

Primary Outcome Measures :
  1. Change in SpO2 [ Time Frame: Before proning and 1 hour after initiation of the prone position ]
    SpO2 was measured by peripheral pulse oximetry.

Secondary Outcome Measures :
  1. Mean Risk Difference in Intubation Rates [ Time Frame: Duration of hospitalization or up to 1 month from admission ]
    The mean risk difference in intubation rates for patients with SpO2 ≥95% vs. <95% 1 hour after initiation of the prone position was assessed.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Consecutive patients with laboratory-confirmed COVID-19 infection who were admitted to the step-down unit at the Columbia University Irving Medical Center in New York between April 6 and 14, 2020 were included. A confirmed case of COVID-19 was defined by a positive result on a reverse transcriptase-polymerase chain reaction (RT-PCR) assay of a specimen collected on a nasopharyngeal swab. Only laboratory-confirmed cases were included.

Inclusion Criteria:

  • Consecutive patients admitted to the Columbia University step-down unit from April 6, 2020.
  • Laboratory confirmed COVID-19 infection with severe hypoxemic respiratory failure defined as respiratory rate ≥30 breaths/min and oxyhemoglobin saturation (SpO2) ≤93% while receiving supplemental oxygen 6 L/min via nasal cannula and 15 L/min via non-rebreather facemask.

Exclusion Criteria:

  • Altered mental status with inability to turn in bed without assistance
  • Extreme respiratory distress requiring immediate intubation, or oxygen requirements less than specified in the inclusion criteria.
